and useful Improvements in Lamps, of

which the following is a specification.

The object of the invention is the production of a lamp especially adapted for use on automobiles which, first, shall be provided with a door or cover detachably secured to the body by means easily and quickly manipulated and which will maintain a tight joint between the door and body; and,-secondly, which shall have the reflector yield ingly or spring supported between the door and body whereby excessive vibrations and clattering will be prevented.

The invention consists in certain novelties of construction and combinations of parts as herein set forth and specified in the claims.

The accompanying drawing illustrates an example of the embodiment of the invention, the parts being constructed and combined according to the best mode. of procedure I have so far devised-for the purpose.

Figure 1 is a vertical section in elevation taken on the line z 'y of Fig. 2. Fig. 2 is a half front elevation view and a half sec-- tional view, the section being taken in front of the reflector. Figs. 3, 4: and 5 are detail views illustrating the means for dctachably locking the door to the body. Fig. 6 is a detail viewpartly in section showing the means for holding the glass or lens in position. Fig. 7 is a detail of the door or cover illustrating the lug which fastens the door to the top of the body. Fig. 8 illustrates in perspective one of the three sets of the yield ing or spring lugs and spring rim for sup porting the reflector.

Referring to the several figures, '1 designates the body or shell. of the lamp of a general concavo-convex shape, and having a cylindrical rim 2 at its front. To the inner surface of this rim are secured by solder at three places, each at equal distances from the others, three inwardly projecting yielding metallic or spring lugs a, a and b, the lug I) being bent outwardly, as shown in Fig. 8, and each lug 01; having a bearing 0 against which the outer peripheral edge of the reflector frlctionally bears when place. The reflector 3 is fashioned to have a circular recess a within which is located so as to project therefrom a cord 5 of yielding textlle material. The metal of the reflector is spun or bent back some distance from the recess 4 for the cord and then turned to form a. disk flange 6, the same being of less diameter than the diameter of the body rim 2 so the flange may bear against the yielding lugs a a and beneath the lugs 15. The flange 6 has three notches 7 which allow the flange to pass the lugs b when the notches register with the lugs and by rotating the reflector upon its axis the reflector flange will become frictionally locked between the lugs a a and the lugs Z2. When the reflector is in its normal position the outer surface of the flange 6 is substantially in the same plane as the outer edge of the rim 2 of the body, as indicatedby the dotted line :20, top of Fig. 1.

The door or cover for the lamp comprises an exterior ornamental molding or ring 8 of a general concavo-convex shape in cross section having an inner edge 9 and an exterior edge 10; an integral interior ring or molding 11. having an exterior cylindrical flange 12 and an interior flange 13 united by a rectangular body portion comprising the vertical part 14 and the horizontal part 15, the flange l3 bearing against the edge 90f the molding 8 and the flange 12 being soldered to the edge 10 of said molding; and a lens or glass 16 hearing against the inner edge 9 of the molding 8 and held in place by a plurality of spring lugs, 17 struck up around the part 15 of the interior molding 11. as shown by Fig. (i.

It will be observed'that when the door or gaged and compressed the cord 5. The glass and the reflector are thus both held in their normal positions under cushioning and spring or yielding tension so they cannot position by novel fastening means.

clatter and so dust cannot pass the glass to the interior of the reflector. j

The door or cover is removably held in The rim 2 has a slot 18 and, the door or cover a lug 19 removably seated within the slot, see

top of Fig. 1 and Fig. 7. The lower inte-' face of the body. A spring 28. may be used to withdrawthe end 22 from the slots when the lever is unlocked. The pivotedlever is operated in one direction and locked by'an operatingor locking lever 29 having a short arm-30 and a long curved'arm 31, the arm 31 bein narrower than the arm 30 and passed through a slot 32 in the body, the

metal adjacent serving as a fulcrum. The

short arm 30 being too wide to pass through the slot, the metal at each edge bears against the metal boundingthe slot. In Fig. 5 and bottom of Fig. l the pivoted lever is shown locked by the short arm 30 turned to engage the power arm of the pivoted lever so it cannot turn, and in Fig. ithe parts are shown in unlocked osition. Turn the handle 31 of the lock ng lever backwardly in Fig. 1 and the end of the pivoted lever is withdrawn from the slot, and the lower v edge of the door or cover may then be pulled out and the lug at the top of the door or cover be lifted out of the slot in the rim, as is obvious.

In replacing the door or cover the lug 19 is inserted in the slot 18 and the lower edge of the cover gently moved into position, the glass. first pressing against the cord 5 and the flange 6 pressing against the yielding lug a a within the edge of the rim andwhen the cover is locked the reflector is securely held so it cannot move and clatter, and the rim 2 of the 'body 'is also held in frictional contact with the door or cover.

v The several parts are easily fashioned, the

locking means easily manipulated, and when assembled for use there is no loose element or elements which can move relative to anotheror one. another and clatter or occasion abrasion or frictional wear-on the parts.

What I claim is: 1. The combinationin a lamp, of a body or shell having a cylindrical rim witha pluralityof sets of yielding lugs disposed about the inner surface of said rim the lugs of each set being located in substantially parallel planes; :1 reflector having a flange with notches whereby the said flange can be placed between the lugs lying in different ioned and the reflector same; a removable door or cover provided with an inner edge, a glass or lens in frictional contact with said ledge, :and an outer edge lappingover the cylindrical rim of the body; and means for detachably locking the door or cover to the rim of the body; the said glass or lens engaging the packing or cord and pressing the flangeof the reflector against thelu'fgs at the inner surface of the rim of the ,body;whereby the glass is cushheld against clattering vibration; f

2. The combination in a lamp, of a body orshell having a cylindrical rim with a plurality of sets of yielding lugsdisposed about the inner surface of said rim, thelugs of each set being locatedin two substantially parallelplanejs; a reflectorjhavinga flange with notch shwhereby the said flange can be placedbetween-thelugs lying in parallel planes and'rjotated aboutits aXisto-alocked positionyapacking 0r cord of yielding material being located in a plane parallel with the flange and in front of the same; a removable door or cover comprising amolding substantially concave-convex in cross section having. an inner edge with a glass or lens in contact therewith and a ring of angular shape in cross section secured to the rear surface of said molding and provided with a part, as 14, with a surface adapted to frictionally engage the disk flange of the A reflector when the cord has been compressed having a rim, a reflector having aflange,

means for supporting the flange of the reflector upon the rim of the body, a packing located upon the reflector and in front of the flange, a door or cover having a glass which engages the said packing and anedge which overlaps the rim of the body, and means for detachably securing the door or cover to the body consisting of a lug upon one of said members seated within a slot in the other member, and a pivoted lever located upon and secured to the interior surface of the body at the opposite side of the body and cover and having an end seated within registering slots in the rim of the body and the cover, means being provided for locking and unlocking said lever.

4.The combination with a lamp body, of a detachable door or cover and means for securing the door or cover to the body consisting of a lug on one of the members seated within a slot in the pther member, a pivoted lever at the opposite edge of the body and cover, said lever secured to the inner surface of the body and the end thereof seated Within a slot in the door or cover, and a looking lever pivoted within a slot in the body, one arm being adapted to engage the pivoted lever and hold it from turning upon its pivot when in one position and releasing the lever when in another position, the other s end of the locking lever being located outside the body and serving as a handle.

In testimony whereof I aflix my signature in presence of two witnesses.
